Bogeyman
Bogeymen are a species of Others that are the embodiment of fear and terror. Described as "Loner Others with a penchant for murder and terror" these beings typically prey on humans. They originate in Limbo and their hatred boils over until they surface, with those who died gruesome deaths more likely to rise.
Types
Bogeymen have human-like forms that enable them to blend into society with ease, with their abilities geared towards targeting humans. An example would be one in particular that steals the faces of other people and wears them like a mask, enabling it to act as that person with no one the wiser, while another forges inconvenient connections that causes conflicts amongst allies.
